T0 aZZ whom it may concern:

Be it known that I, JAooB F. FREDERICK, a citizen of the United States,residing at Chicago, in the county of Cook and State of Illinois, haveinvented new and useful Improvements in Attachments for PrintingPresses, of which the following is a specification.

This invention relates to an attachment for a printing press and has forits primary object the construction of an apparatus whereby a suctionaction may be created at required points to assure proper engage nientbetween the traveling sheets and tapes, and besides, the properassociation of the various sheets upon the jogger board.

An object of the invention is to provide means for creating the suctionfor accomplishing the foregoing result and to use a portion of theexhaust air to cool the ink rolls, which in practice are subject toexcessive heating action which shortens the life of the rolls.

A feature of my invention is the novel manner of constructing andassociating the parts so that, in an inexpensive manner, I have beenable to create a suction for holding the sheets in their properposition, and besides to cool the ink rolls and support the gas burnerin its most advantageous position.

With these and other objects in view the invention will be betterunderstood from the following detailed description taken in con nectionwith the accompanying drawing wherein:

Fig. 1 is a diagrammatic view illustrating my invention in appliedposition.

Fig. 2 is a top plan view of the casing with the nozzles connectedthereto.

Fig. 3 is an end elevation of thecasing.

Fig. i is a sectional view through the spray device.

Fig. 5 is a sectional view through the exhaust pipe of the fan.

' Figs. 6 and 7 are sectional views through one of the nozzles.

Again referring to the drawing illustrating my invention in adiagrammatic manner the numeral 1 designates a casing completelyenclosed and of a shape to be received between the traveling tapes 2.One wall of the casing is provided with a groove 3 for receiving the flyrest 4 while the other end is provided with a plurality of hooksSpecification of Letters Patent.

5 for engagement over the delivery arm of the press. From thisconstruction it will be seen that the casing may be very readilyconnected to the press and properly associated with the traveling tapes.The entire upper surface of the casing is provided with a plurality ofair-intake holes 6 decreasing in size toward the delivery arm of thepress. Adjacent the groove 3 the casing is further provided with theholes 7 to increase the efliciency of the attachment. Arranged on thetable A beneath the fly b, and around the jogger board C of the press,at the most advantageous points, is a plurality of nozzles 8 of anysuitable construction, but for the purpose of illustration shown asconsisting of an open front boxlike casing 9, communicating with theinterior of the casing 1 by the tube 10.

In a diagrammatic manner I have illustrated a suction device in the formof a fan 11, the intake conduit 12 of which communicates with theinterior of the casing 1 while the exhaust conduit 13 may have itsoutlet end arranged at any suitable point.

As far as I have proceeded it will be seen that upon operation of thefan 11, the reduction of air pressure within the casing causes air to besucked through the holes 6 and 7 and thus the suction action is reliedupon to cause the air currents created to act on the traveling sheets ina manner to effectively hold them in engagement with the tapes and thusthey are prevented from becoming dislocated from their proper position.Simultaneously with this action air is sucked from the jogger board intothe nozzles 8 which action causes the air currents created to force thesheets into their proper relation upon the jogger board and therebydispense with the services of an at tendant to properly arrange thesheets. It is, of course, to be understood that this action may beaccomplished in various other manners than illustrated as the drawingsare prepared in a diagrammatic manner to simplify the operation.

In practice it is advantageous to cool the ink rolls so as to prolongthe life thereof and to accomplish this I have shown means fordischarging a portion of the exhaust air on to the rolls. This meansconsists of a plurality of spray holes 14: in the bottom of the casingwhich communicate with the hood Patented Ma y 2,1922.

15 that in turn is connected by a pipe 16 with the exhaust pipe 13. Avalve 17 in the exhaust pipe 13 controls the flow 01 the exhaust airwhich has the efiect-ot regulating the passage of this exhaust airthrough the pipe 16 and through the openings 14 on to the ink rolls Tocomplete the invention Ihave illustrated a burner 18 supported by thecasing.

From the foregoing description taken in connection with the accompanyingdrawings itwillbe apparent that, in a very inexpensive manner, I am ableto provide an apparatus that will create air currents in a direction toregulate the travel of the sheets, and besides, to subject the ink rollsto air currents for cooling the same.

vAs the apparatus may be constructed in various other manners and theparts associated in-ditierent relations I do not desire to be limited inany manner except as set forth in the claims hereunto appended.

Having thus described my invention what I claim is:

1. In combination with a printing press embodyinga jogger board and aplurality of, traveling tapes, of a casing shaped and constructed to bearranged between the moving tapes and provided with a plurality of airintake holes, means tending to create a vacuum in the casing, and aplurality of nozzles arranged around the jogger board and communicatingwith said casing.

In combination with a printing press embodying a jogger board and aplurality of traveling tapes, of a casing disposed between said tapesand provided with a plurality of openings, a plurality of nozzlesarranged around said jogger board, tubes connecting said casing and saidnozzles, and" i vice arranged between said tapes, means for creating asuction in said device, an auxiliary suction device arranged around saidjogger board, and means receiving air from the suction means anddirecting the same upon said inking rolls.

5. In combination with a printing press embodying a plurality oftraveling tapes and inking rollers disposed adjacent thereto, of asubstantially rectangular casing disposed between said tapes andprovided with a plurality of air-intake openings, means for creating asuction in said casing and means for discharging a portion of the airfrom said suction means upon said inking rolls.

6. in combination with a printing press embodying a jogger board, aplurality of traveling tapes and inking rollers located adjacent to saidtapes, of a casing disposed between said tapes and provided with aplurality of openings in the top and in one end thereof, means forcreating a suction in said casing, means associated with the suctionmeans for discharging air upon said inking rollers, and nozzles arrangedaround the jogger board and communicating with said casing.

7. in combination with a printing press embodying a jogger board, aplurality of traveling tapes and inking rollers located adjacent to saidtapes, of a casing disposed between said tapes and provided with aplurality of openings, a plurality of nozzles arranged around saidjogger board and com municating with said casing, and a rotary fan fordirecting air from said casing and discharging a portion thereof uponsaid inking rollers.

8. In combination with a printing press embodying a jogger board, aplurality of traveling tapes and inking rollers located adjacent to saidtapes, of a casing disposed between said tapes, a plurality of nozzlesarranged around the jogger board and communicating with said casing, asuction fan located adjacent to said tapes and communicating with theinterior of said casing, a spray device supported by the casing in adirection to discharge air upon said inking rollers, a pipe establishingcommunication between the spray device and the exhaust of the fan and avalve controlling the eX- haust Of the fan to thereby control the airpassing through said pipes to the spray device.

In testimony whereof I atlix my signature.

JACOP FRANKLIN FREDERICK.
